Conditions at Pico Alto in August
August: Full Winter Assault
August is another heavyweight month, with the average swell height still pinned at 6.2ft (1.9m) and the period back up to 13.0s. SSW swell dominates with 71 percent of the energy, while S swell adds 17 percent. More than 37 percent of observations fall in the 5-6.5ft (1.5-2m) range, and nearly 20 percent reach 6.5-8ft (2-2.5m), with a small amount of 8ft-plus (2.5m+) surf mixed in. Pico Alto is in full charging mode.
Wind is almost uniformly from the south-southwest, with SSW alone making up over 50 percent of the wind rose and S adding another 43 percent. Ideal offshore flow remains absent. Water temperature drops to its cooler side at 15.5°C, and air temperatures average 16.8°C. Look for those rare high-pressure mornings when the Andes drainage wind produces an offshore breeze; otherwise expect challenging, bumpy surfaces on otherwise epic swell.
